yes…with the caveats that this solution will only work with a fixed width site and it works in Safari, Firefox and Chrome on a Mac - IE results may vary - do not expect it to work in IE8 or earlier.
1) go to ATO->Style & configure LAYOUT->Layout WIDTH and type (FLUID or FIXED) and set it to '1000px'
2) go to ATO->Style & configure SIDEBARS and set the right sidebar to 200px
3) add the following to your CSS Inserts
HTML Code:
#layout tbody {width: 1000px;}
#layout tr#bodyrow {
width: 1000px;
box-shadow: 10px 10px 5px #000000;
margin-bottom: 15px;
display: block;
border: solid 1px #000000;
}
td#middle {width: 800px;}
td#right {width: 200px;}
if you want a different width make sure to change the three widths in the CSS and make sure the middle and right add to the total.
